Abstract
A process, and a system configured to perform the process, is provided which oxidizes lignin present in filtrates into methanol by feeding into a lignin-containing feedstock an oxidative agent in a reactor. The process includes: providing, in a reactor, a feedstock comprising lignin in an aqueous medium; feeding into the feedstock at least one oxidative agent to produce a reaction mixture in which methoxyl groups of the lignin are oxidized into methanol; adjusting the pH of the reaction mixture to a value in a range of 5 to 14; and operating the reactor at a temperature in a range of 50° C. to 100° C.
